I took Dylan into a portable potty during one of Sebastian's soccer practices. He was extremely curious about the entire setup: The makeshift urinal, the disgusting blue liquid, the lack of a sink, etc. During our visit into the porta-potty discussion inside the overheated unit, this conversation took place:
Dylan: . . . and what is that pipe next to me?
Me: The pipe coming out of the part that you are pooping in?
Dylan: Yeah, that pipe that goes up.
Me: That's for ventilation, to let the gas and fumes go all the way up and out.
Dylan: Does it go all the way to God?
So, when was the last time you witnessed to someone in a single-unit portable toilet?
